Indicating callers for incoming voice calls on a shared speech-enabled device

ABSTRACT

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for indicating callers for incoming voice calls to a shared device among multiple users. The methods, systems, and apparatus include actions receiving an incoming voice call, determining a calling number and a called number from the incoming voice call, identifying a user account that corresponds to the called number, determining a contact name for the calling number based on contact entries for the user account, and providing the audible contact name for output to the device speaker.

FIELD

This specification generally relates to shared speech-enabled devices.

BACKGROUND

Speech-enabled devices may be used to respond to speech from users. For example, a speech-enabled device may be shared by multiple users in a home so a first user may say “OK Computer, play music,” the speech-enabled device may respond to the utterance by playing music, then a second user may say “OK Computer, stop music,” and the speech-enabled device may then respond to the second utterance be stopping the music.

SUMMARY

Implementations described herein enable a shared device to be used by multiple users to receive incoming phone calls. For example, a shared speech-enabled device left on a counter top within a home may be used by multiple people to receive incoming phone calls. The shared device may receive incoming phone calls placed to phone numbers of each of the multiple users of the shared device. For example, the shared device may be used by two users so receive incoming phone calls to the phone number “(111) 111-1111” of a first user and the phone number “(222) 222-2222” of a second user.

Despite being shared between multiple users, the shared device is able to indicate to users a name from a contact entry instead of a phone number that initiated the call. For example, a user may have forgotten that a phone number “(123) 456-7890” is their aunt's phone number so it may be helpful for a device to indicate that an incoming call was from “Aunt Jen” instead of from the phone number “(123) 456-7890,” or additionally to indicating that the phone call is from the phone number “(123) 456-7890.” Users may then decide whether to answer the incoming call or not answer the incoming call based on the indication of who is calling.

In a device that is not shared, e.g., a phone used by a single user and associated with only the phone number of that single user, numbers may be associated with only a single contact entry. For example, the phone number “(123) 456-7890” may correspond to only a single contact entry for a single user. However, different users may have different contact entries for the same number. For example, a first user of the shared device may have a contact entry of “Aunt Jen” associated with the number “(123) 456-7890” and a second user of the shared device may have a contact entry of “Sis” associated with the number “(123) 456-7890.” Additionally, the first user may have a different contact entry with the same name as a contact entry of the second user, “Sis,” associated with the different number “(234) 567-8901.”

Accordingly, to indicate a caller for an incoming call, a shared device may initially determine which number is being called and then determine the caller based on contact entries of the user that corresponds to the number that is called. For example, the speech-enabled device may determine that an incoming call is for the phone number “(222) 222-2222” which corresponds to an account of “Jane,” then determine that a name of “Aunt Jen” corresponds to the calling number of “(123) 456-7890” based on a contact entry named “Aunt Jen” for “Jane,” and, in response, output “Incoming call for Jane from Aunt Jen.”

Accordingly, in some implementations an advantage may be that multiple users of a shared device are able to identify who is calling by providing for the same number that is calling to be indicated differently based on contact entries for different users. For example, the same number may be indicated as “Mom” or as “Mother in law” depending on the number that was called. Another advantage may be that determination of a name of a caller may be efficient. For example, the search scope for a contact entry with a number that matches the number that is calling may be focused by limiting the contact entries considered to only the contact entries for a user account of a user that is being called. Yet another advantage may be that phone contacts may be stored on a server remote from the shared device instead of on the shared device so security of phone contacts may be increased. This may be particularly beneficial for shared devices that have limited local resources, such as memory or processing power. Implementations may therefore balance competing requirements of limited local resources for storage and administration of contacts with quick and efficient provision of those contacts when receiving calls at a shared device.

In some aspects, the subject matter described in this specification may be embodied in methods that may include the actions of receiving an incoming voice call, determining a calling number and a called number from the incoming voice call, identifying a user account that corresponds to the called number, determining a contact name for the calling number based on contact entries for the user account, and providing the contact name for output.

In some implementations, identifying a user account that corresponds to the called number includes determining that the called number matches a number that corresponds with the user account and in response to determining that the called number matches that number associated with the user account, identifying the user account. In certain aspects, determining that the called number matches a number that corresponds with the user account includes obtaining multiple numbers that each separately correspond with a respective one of multiple user accounts and determining that one of the multiple numbers that are obtained matches the called number.

In some aspects, determining a contact name for the calling number based on contact entries for the user account includes providing, by a speech-enabled device and to a voice-enabled virtual assistant server, a query that includes the user account and the calling number and receiving, by the speech-enabled device and from the voice-enabled virtual assistant server, the contact name in response to the query. In some implementations, receiving, from the voice-enabled virtual assistant server, the contact name in response to the query includes receiving audio data that represents synthesized speech of the contact name.

In certain aspects, determining a contact name for the calling number based on contact entries for the user account includes obtaining contact entries for the user account, determining that the calling number matches a number that corresponds to a particular contact entry of the contact entries for the user account and in response to determining that the calling number matches the number that corresponds to the particular contact entry of the contact entries for the user account, selecting the contact name from the particular contact entry.

In some implementations, receiving an incoming voice call includes receiving an incoming voice call that indicates the calling number and the called number. In some aspects, providing the contact name for output includes outputting synthesized speech of the contact name through a speaker. In certain aspects, the incoming voice call includes a Voice over Internet Protocol (VoIP) call. In some implementations, actions include providing a name of the user account for output.

Other implementations of this and other aspects include corresponding systems, apparatus, and computer programs, configured to perform the actions of the methods, encoded on computer storage devices. A system of one or more computers can be so configured by virtue of software, firmware, hardware, or a combination of them installed on the system that in operation cause the system to perform the actions. One or more computer programs can be so configured by virtue of having instructions that, when executed by data processing apparatus, cause the apparatus to perform the actions.

Details of one or more implementations of the subject matter described in this specification are set forth in the accompanying drawings and the description below. Other features, aspects, and potential advantages of the subject matter will become apparent from the description, the drawings, and the claims.

DETAILED DESCRIPTION

FIGS. 1A-1B are block diagrams that illustrate example interactions with a shared device indicating a caller for an incoming call. FIGS. 1A-1B show a system 100 that includes a shared speech-enabled device 125, also referred to as speech-enabled device 125, that can be used by a user to receive incoming calls. The system 100 further includes a call provider 110 that provides an incoming call to the speech-enabled device 125, an assistant server 140 that determines a name for the phone number that is calling, and a contact database 150 that stores contact entries for user accounts.

The speech-enabled device 125 may receive incoming voice calls for multiple users and then indicate names of callers from contact entries of the user that was called. For example, FIG. 1A illustrates how the speech-enabled device 125 may receive an incoming call for the phone number “(111) 111-1111” from the phone number “(333) 333-3333” and, in response, output synthesized speech of “Incoming call for John from Grandpa.” In another example, FIG. 1B illustrates how the speech-enabled device 125 may receive an incoming call for the different phone number “(222) 222-2222” from the same phone number “(333) 333-3333” and, in response, output synthesized speech of “Incoming call for Matt from (333) 333-3333.” The output of the speech-enabled device 125 may be different as the contact entries of the user account corresponding to the number that is called are different. For example, the user account of “John” may include a contact entry named “Grandpa” with a phone number of “(333) 333-3333” while the user account of “Matt” may not include any contact entry with a phone number of “(333) 333-3333.” A voice call may be a call that includes only audio or a call that includes audio and one or more other components, e.g., video.

In more detail, the speech-enabled device 125 may perform actions in response to detecting an utterance including a predetermined phrase, also referred to as a hotword, that a user speaks to address the speech-enabled device 125. A hotword may be “OK Computer” or some other phrase, that a user must speak immediately preceding any request that the user says to the speech-enabled device 125. For example, in response to a user saying “OK Computer, answer call,” the speech-enabled device 125 may answer an incoming call. In another example, in response to a user saying “OK Computer, decline call,” the speech-enabled device 125 may decline an incoming call. Declining an incoming may include one or more of sending the incoming call straight to a voicemail of the user account or no longer indicating that the call is incoming. The speech-enabled device 125 may receive utterances using one or more microphones included in the speech-enabled device 125 and output audible responses to the utterances through one or more speakers included in the speech-enabled device 125.

The speech-enabled device 125 may store user account information for each known user of the speech-enabled device 125. For example, the speech-enabled device 125 may store a first set of user account information 132 for the known user “John,” a second set of user account information 134 for the known user “Jane,” and a third set of user account information 136 for the known user “Matt.”

The user account information may be stored in response to users registering to use the speech-enabled device 125. For example, the users “John,” “Jane,” and “Matt” may register with the speech-enabled device 125 and, in response, the user account information for each user may be stored on the speech-enabled device 125. Registering with the speech-enabled device 125 may enable the users to personalize interactions with the speech-enabled device 125. For example, registering with the speech-enabled device 125 may enable the speech-enabled device 125 to recognize speech from a particular user and then provide responses specific to that user. Additionally or alternatively, registering with the speech-enabled device 125 may enable users to receive incoming voice calls through the speech-enabled device 125. For example, “John” and “Matt” may receive incoming phone calls as they both registered and indicated that they would like to receive calls to “(111) 111-1111” and “(222) 222-2222,” respectively.

The user account information of a user may indicate speaker identification features that may be used to recognize whether a speaker is the user. For example, the first set of user account information 132 for “John” may store mel-frequency cepstral coefficients (MFCCs) features, which collectively can form a feature vector, that represent the user “John” previously saying a hotword multiple times. Recognition of the speaker may be used to personalize responses to utterances.

In some implementations, a user may register as a known user through a companion application on a mobile computing device where the mobile computing device is in communication with the speech-enabled device 125 via a local wireless connection. For example, a user “John” may log into his account through a companion application on his phone, then indicate in the companion application that he would like to register as a known user of the speech-enabled device 125, and then say a hotword multiple times into his phone.

As part of the registration, or afterwards, a user may indicate whether the user would like to associate a phone number for use to receiving incoming calls on the speech-enabled device 125. For example, the user “John” may indicate he would like to receive incoming calls to the phone number “(111) 111-1111” on the speech-enabled device 125 and, in response, the speech-enabled device 125 may store a phone number 133 in John's account information 132. In another example, the user “Matt” may indicate he would like to receive incoming calls to the phone number “(222) 222-2222” on the speech-enabled device 125 and, in response, the speech-enabled device 125 may store a phone number 137 in Matt's account information 136.

The user account information of a user may indicate a name of the user account. For example, the first set of user account information 132 for “John” may store the name “John.” The name of the user account may identify the user to which the account belongs. For example, the name “John” of the user account may indicate that the account belongs to John and that information stored in the account information is for “John.”

The speech-enabled device 125 may receive calls through a call provider 110. For example, the call provider 110 may be a server of a Voice over Internet Protocol (VoIP) provider that routes calls to the phone number “(111) 111-1111” to both the speech-enabled device 125 and a phone associated with the user account of the user “John.” In another example, the call provider 110 may be a system of cellular network provider that routes calls to the phone number “(111) 111-1111” to both the speech-enabled device 125 and a phone associated with the user account of the user “John.” In a particular example, the speech-enabled device 125 may receive, from the call provider 110, an incoming call for the phone number “(111) 111-1111” from “(333) 333-3333” (as indicated by the arrow labeled A in FIG. 1A).

In response to receiving a call, the speech-enabled device 125 may identify a user account that corresponds to the phone number that was called. For example, in response to receiving the incoming call for the phone number “(111) 111-1111” from “(333) 333-3333,” the speech-enabled device 125 identify a user account of “John” (as indicated by the arrow labeled B in FIG. 1A).

The speech-enabled device 125 may identify a user account that corresponds to the phone number that was called based on determining that the phone number that was called matches a phone number stored in account information on the speech-enabled device 125. For example, the speech-enabled device 125 may access the phone number “(111) 111-1111” for the user account of “John” and “(222) 222-2222” for the user account of “Matt” from the account information stored on the speech-enabled device 125, and then determine that the phone number “(111) 111-1111” that was called matches to accessed phone number “(111) 111-1111” from the user account of “John.” Two phone numbers may be considered to match when the phone numbers are identical.

The speech-enabled device 125 may then provide an indication of the user account that is being called and the phone number that was called to the assistant server 140. For example, the speech-enabled device 125 may provide a query for a contact name to the assistant server 140, where the query includes (i) an identifier that uniquely identifies the user account of “John” from other user accounts and (ii) the phone number “(333) 333-3333” (as indicated by the arrow labeled C in FIG. 1A). In some implementations, the identifier may be an authentication token that both uniquely identifies the user account and also authenticates the speech-enabled device 125 as a device that should have access to in information based on contact entries of the user account.

The speech-enabled device 125 may then receive a contact name from the assistant server 140 in response to the indication. For example, the speech-enabled device 125 may receive a response that is synthesized speech of “Incoming call for John from Grandpa” (as indicated by the arrow labeled F in FIG. 1A). In another example, the speech-enabled device 125 may receive text of “Incoming call for John from Grandpa.”

The speech-enabled device 125 may then output the contact name. For example, the speech-enabled device 125 may output received synthesized speech of “Incoming call for John from Grandpa” on a speaker (as indicated by the box labeled G in FIG. 1A). In another example, the speech-enabled device 125 may synthesize speech from received text of “Incoming call for John from Grandpa” and then output the synthesized speech on a speaker. In yet another example, the speech-enabled device 125 may display text of “Incoming call for John from Grandpa” on a screen.

The speech-enabled device 125 may then receive a query from a user in response to the output of the contact name. For example, the speech-enabled device 125 may receive a query of “OK Computer, answer call” from a user (as indicated by the box labeled H in FIG. 1A). The speech-enabled device 125 may then answer the call in response to the query and the user may then talk through the speech-enabled device 125 with the other person that called them. In receiving the utterance, the speech-enabled device 125 may determine that an utterance includes a hotword, in response, provide a representation of “OK computer, answer call” to the assistant server 140, receive an instruction from the assistant server 140 that triggers the speech-enabled device 125 to answer a call, and, in response, answer the call.

The assistant server 140 may be a server that is remote from the speech-enabled device and that provides a response to both the indication of the user account that is being called and the phone number. For example, the assistant server 140 may provide a response of “Incoming call for John from Grandpa” in response to a query that includes the identifier of the user account of “John” and the phone number “(333) 333-3333” (as indicated by the arrow labeled F in FIG. 1A).

The assistant server 140 may provide the response by determining a contact name for the calling phone number based on contact entries of the user account. For example, the assistant server 140 may determine that the phone number “(333) 333-3333” matches the phone number of a contact entry named “Grandpa” for the user account of “John,” in response, synthesize speech saying “Incoming call for John from Grandpa,” and then provide the synthesized speech to the speech-enabled device 125. In another example, the assistant server 140 may determine that the phone number “(333) 333-3333” matches the phone number of a contact entry named “Grandpa” for the user account of “John,” in response, provide text of “Incoming call for John from Grandpa” to the speech-enabled device 125 to then synthesize speech from the text.

The assistant server 140 may determine a contact name for a calling phone number by obtaining contact entries of the user account identified that are stored in a contact database 150. For example, the assistant server 140 may provide a query to the contact database 150 for all contact entries stored for the user account of “John.” In some implementations, the contact entries stored in the contact database 150 may be inaccessible to the speech-enabled device 125. In some implementations, the contact database 150 may be incorporated in the assistant server 140 and contacts may similarly not be stored on the speech-enabled device 125.

In some implementations, the assistant server 140 may not be able to determine a contact name for a calling phone number from contact entries of a user account. For example, the assistant server 140 may determine that the phone number “(555) 555-5555” does not match the phone number of any contact entry for the user account of “John,” and, in response, determine to provide the phone number of the caller instead of a contact name from a contact entry, e.g., provide text of “Incoming call for John from (555) 555-5555” to the speech-enabled device 125 to then synthesize speech from the text or provide synthesized speech of “Incoming call for John from (555) 555-5555.”

In some implementations, in response to not being able to determine a contact name for a calling phone number from contact entries of a user account, the assistant server 140 may attempt to search for a name for the phone number from publicly available information. For example, the assistant server 140 may search a knowledge graph for an entity that is associated with a phone number of “(555) 555-5555,” determine that “Company X” is associated with that phone number, and in response, provide a response of “Incoming call for John from Company X” or “Incoming call for John from (555) 555-5555 which may correspond to Company X based on publicly available information. In another example, the assistant server 140 may search a knowledge graph for an entity that is associated with a phone number of “(555) 555-5555,” determine that no entity is associated with that phone number, and in response, provide a response of “Incoming call for John from (555) 555-5555.”

In some implementations, the speech-enabled device 125 may be a local front-end device that handles queries in cooperation with an assistant server 140. For example, when the speech-enabled device 125 receives an utterance “OK Computer, answer call,” the speech-enabled device 125 may detect when a speaker says a hotword “OK Computer,” classify a user as “John” based on speaker identification features in the utterance of “OK Computer,” and provide a representation of “answer call,” an indication that the speaker is “John,” and an indication that a call is incoming to a server. The server may then transcribe “answer call,” determine that the text “answer call” corresponds to an action of answering a call, determine from the indication that a call is incoming so a call can be answered, and, in response, provide an instruction of “answer call” to the speech-enabled device 125.

In another example, when the speech-enabled device 125 receives an utterance “OK Computer, decline call,” the speech-enabled device 125 may detect when a speaker says a hotword “OK Computer,” classify a user as “John” based on speaker identification features in the utterance of “OK Computer,” and provide a representation of “answer call,” an indication that the speaker is “John,” and an indication that a call is incoming to a server. The server may then transcribe “decline call,” determine that the text “decline call” corresponds to an action of declining a call, determine from the indication that a call is incoming so a call can be declined, and, in response, provide an instruction of “decline call” to the speech-enabled device 125.

FIG. 1B shows another example where the call provider 110 provides the speech-enabled device 125 a call for “(222) 222-2222” incoming from “(333) 333-3333” (as indicated by the arrow labeled A in FIG. 1B). The speech-enabled device 125 then determines that the called number of “(222) 222-2222” corresponds to a user account of “Matt” (as indicated by the arrow labeled B in FIG. 1B). The speech-enabled device 125 then provides a query for a contact name to the assistant server 140, where the query includes an authentication token for a user account of “Matt” and includes the called number of “(333) 333-3333” (as indicated by the arrow labeled C in FIG. 1B). In response to receiving the query, the assistant server 140 then requests and receives in response contact entries for the user account of “Matt” from the contact database 150 (as indicated by the arrow labeled D in FIG. 1B). The assistant server 140 then determines that the calling number of “(333) 333-3333” does not match the phone number stored for any contact entry for the user account of “Matt” (as indicated by the arrow labeled E in FIG. 1B). The assistant server 140 then provides a response of “Incoming call for Matt from (333) 333-3333 (as indicated by the arrow labeled E in FIG. 1B). The speech-enabled device 125 may then output “Incoming call for Matt from (333) 333-3333” through a speaker (as indicated by the arrow labeled G in FIG. 1B) and receive a response from a user saying “OK Computer, decline call” (as indicated by the arrow labeled H in FIG. 1B).

Different configurations of the system 100 may be used where functionality of the speech-enabled device 125, the call provider 110, the assistant server 140, and the contact database 150 may be combined, further separated, distributed, or interchanged. For example, the speech-enabled device 125 may perform some of the actions described by the assistant server 140. In particular, the speech-enabled device 125 may receive the utterance “OK Computer, answer call,” transcribe the utterance into “OK Computer, answer call,” determine that the transcription “answer call” corresponds to an action of answering a call, determine that a call is incoming, and, in response, answer the call. In another example, the speech-enabled device 125 may store all contacts of all known users that are registered to use the particular speech-enabled device 125 and then when a phone call is incoming, similarly only search the contact entries of the user account that corresponds to the number that was called to identify a contact name for the caller.

FIG. 2 is a flow diagram that illustrates an example of a process 200 for indicating a caller for an incoming call. The operations of the process 200 may be performed by one or more computing systems, such as the system 100 of FIGS. 1A-1B.

The process 200 includes receiving an incoming voice call (210). For example, the speech-enabled device 125 may receive from the call provider 110 an incoming call for “(111) 111-1111” from “(333) 333-3333.”

The process 200 includes determining a calling phone number and a called phone number from the incoming voice call (220). For example, the speech-enabled device 125 may extract the calling phone number of “(333) 333-3333” and the called phone number of “(111) 111-1111” from the incoming phone call.

The process 200 includes identifying a user account that corresponds to the called phone number (230). For example, the speech-enabled device 125 may identify the user account of “John” in response to searching account information of known users stored on the speech-enabled device 125 for a user account with a phone number of “(111) 111-1111,” and determining that the user account “John” includes the phone number.

The process 200 includes determining a contact name for the calling phone number based on contact entries for the user account (240). For example, the speech-enabled device 125 may determine a contact name of “Grandpa” for the calling phone number of “(333) 333-3333” based on contact entries for the user account “John.” As discussed above, the speech-enabled device 125 may determine the contact name by providing a query identifying a user account and the calling phone number to the assistant server 140, and then receiving a response that indicates the contact name. For example, the speech-enabled device 125 may provide the assistant server 140 a query for a contact name, where the query includes “8704584” that is an authentication for the user account of “John” and the number “3333333333” and, in response, the virtual server 140 may provide an audio representation of synthesized speech of “Incoming call for John from Grandpa.”

While some description is provided regarding the use of phone numbers and phone calls, in some implementations other identifiers besides phone numbers or numbers may be used. For example, some implementations may use e-mail addresses, provider specific usernames or provider specific handles that may be used to identify a caller and a call recipient instead of using phone numbers.

Additionally or alternatively, in some implementations, the speech-enabled device 125 may verify that a user may answer an incoming call before answering the call. For example, the speech-enabled device 125 may verify that a user John can answer an incoming call for John before answering the call. The speech-enabled device 125 may verify that a user may answer an incoming call by performing speaker identification. For example, the speech-enabled device 125 may verify that a user that says “OK Computer, answer call” is a known user John. The speech-enabled device 125 may perform speaker verification using speaker identification features stored on the speech-enabled device 125 for known users. For example, the speech-enabled device 125 may determine that MFCCs for “OK Computer, answer call” match stored MFCCs for the known user John and, in response, determine that the user is John.

The speech-enabled device 125 may allow users to answer their own incoming calls. For example, the speech-enabled device 125 may determine that John said “OK Computer, answer call” for an incoming call for John and, in response, answer the call. In another example, the speech-enabled device 125 may determine that John said “OK Computer, answer call” for an incoming call for Matt and, in response, not answer the call and output “Sorry this call is for Matt and you are not authorized to answer calls for Matt.”

In some implementations, the system 100 may enable users to authorize other users to answer incoming calls for them. For example, a known user John may specify that he authorizes known user Matt to answer calls for him. The speech-enabled device 125 or the assistant server 140 may store an indication that the known user authorizes another known user to answer their calls. In some implementations, a user may specify that any user can answer incoming calls for them and the speech-enabled device 125 or the assistant server 140 may store a corresponding indication.

According, an example process for answering a call may include, receiving an utterance that indicates to answer an incoming call, determining an identity of the speaker, determining whether the speaker is authorized to answer calls for the user being called, and, in response to determining that the speaker is authorized to answer calls for the user being called, answering the call. For example, the speech-enabled device 125 may receive an utterance of “OK Computer, answer call” spoken by the user Matt for a call announced as for John, determine that Matt spoke the utterance, determine that Matt is authorized to answer incoming calls for the user John based on an indication stored by the assistant server 140 that John has authorized Matt to answer his calls, and, in response, answer the call. In another example, the speech-enabled device 125 may receive an utterance of “OK Computer, answer call” spoken by the user John for a call announced as for Matt, determine that John spoke the utterance, determine that John is not authorized to answer incoming calls for the user Matt based on no indication stored by the assistant server 140 that Matt has authorized John to answer his calls, and, in response, not answer the call.

FIG. 3 shows an example of a computing device 300 and a mobile computing device 350 that can be used to implement the techniques described here. The computing device 300 is intended to represent various forms of digital computers, such as laptops, desktops, workstations, personal digital assistants, servers, blade servers, mainframes, and other appropriate computers. The mobile computing device 350 is intended to represent various forms of mobile devices, such as personal digital assistants, cellular telephones, smart-phones, and other similar computing devices. The components shown here, their connections and relationships, and their functions, are meant to be examples only, and are not meant to be limiting.

The computing device 300 includes a processor 302, a memory 304, a storage device 306, a high-speed interface 308 connecting to the memory 304 and multiple high-speed expansion ports 310, and a low-speed interface 312 connecting to a low-speed expansion port 314 and the storage device 306. Each of the processor 302, the memory 304, the storage device 306, the high-speed interface 308, the high-speed expansion ports 310, and the low-speed interface 312, are interconnected using various busses, and may be mounted on a common motherboard or in other manners as appropriate. The processor 302 can process instructions for execution within the computing device 300, including instructions stored in the memory 304 or on the storage device 306 to display graphical information for a graphical user interface (GUI) on an external input/output device, such as a display 316 coupled to the high-speed interface 308. In other implementations, multiple processors and/or multiple buses may be used, as appropriate, along with multiple memories and types of memory. Also, multiple computing devices may be connected, with each device providing portions of the necessary operations (e.g., as a server bank, a group of blade servers, or a multi-processor system).

The memory 304 stores information within the computing device 300. In some implementations, the memory 304 is a volatile memory unit or units. In some implementations, the memory 304 is a non-volatile memory unit or units. The memory 304 may also be another form of computer-readable medium, such as a magnetic or optical disk.

The storage device 306 is capable of providing mass storage for the computing device 300. In some implementations, the storage device 306 may be or contain a computer-readable medium, such as a floppy disk device, a hard disk device, an optical disk device, or a tape device, a flash memory or other similar solid state memory device, or an array of devices, including devices in a storage area network or other configurations. Instructions can be stored in an information carrier. The instructions, when executed by one or more processing devices (for example, processor 302), perform one or more methods, such as those described above. The instructions can also be stored by one or more storage devices such as computer- or machine-readable mediums (for example, the memory 304, the storage device 306, or memory on the processor 302).

The high-speed interface 308 manages bandwidth-intensive operations for the computing device 300, while the low-speed interface 312 manages lower bandwidth-intensive operations.

In addition, an external interface 362 may provide communication with the processor 352, so as to enable near area communication of the mobile computing device 350 with other devices. The external interface 362 may provide, for example, for wired communication in some implementations, or for wireless communication in other implementations, and multiple interfaces may also be used.

The memory 364 stores information within the mobile computing device 350. The memory 364 can be implemented as one or more of a computer-readable medium or media, a volatile memory unit or units, or a non-volatile memory unit or units. An expansion memory 374 may also be provided and connected to the mobile computing device 350 through an expansion interface 372, which may include, for example, a SIMM (Single In Line Memory Module) card interface. The expansion memory 374 may provide extra storage space for the mobile computing device 350, or may also store applications or other information for the mobile computing device 350. Specifically, the expansion memory 374 may include instructions to carry out or supplement the processes described above, and may include secure information also. Thus, for example, the expansion memory 374 may be provided as a security module for the mobile computing device 350, and may be programmed with instructions that permit secure use of the mobile computing device 350. In addition, secure applications may be provided via the SIMM cards, along with additional information, such as placing identifying information on the SIMM card in a non-hackable manner.

The memory may include, for example, flash memory and/or NVRAM memory (non-volatile random access memory), as discussed below. In some implementations, instructions are stored in an information carrier that the instructions, when executed by one or more processing devices (for example, processor 352), perform one or more methods, such as those described above. The instructions can also be stored by one or more storage devices, such as one or more computer- or machine-readable mediums (for example, the memory 364, the expansion memory 374, or memory on the processor 352). In some implementations, the instructions can be received in a propagated signal, for example, over the transceiver 368 or the external interface 362.

The mobile computing device 350 may communicate wirelessly through the communication interface 366, which may include digital signal processing circuitry where necessary. The communication interface 366 may provide for communications under various modes or protocols, such as GSM voice calls (Global System for Mobile communications), SMS (Short Message Service), EMS (Enhanced Messaging Service), or MMS messaging (Multimedia Messaging Service), CDMA (code division multiple access), TDMA (time division multiple access), PDC (Personal Digital Cellular), WCDMA (Wideband Code Division Multiple Access), CDMA2000, or GPRS (General Packet Radio Service), among others. Such communication may occur, for example, through the transceiver 368 using a radio-frequency. In addition, short-range communication may occur, such as using a Bluetooth, WiFi, or other such transceiver (not shown). In addition, a GPS (Global Positioning System) receiver module 370 may provide additional navigation- and location-related wireless data to the mobile computing device 350, which may be used as appropriate by applications running on the mobile computing device 350.

The mobile computing device 350 may also communicate audibly using an audio codec 360, which may receive spoken information from a user and convert it to usable digital information. The audio codec 360 may likewise generate audible sound for a user, such as through a speaker, e.g., in a handset of the mobile computing device 350. Such sound may include sound from voice telephone calls, may include recorded sound (e.g., voice messages, music files, etc.) and may also include sound generated by applications operating on the mobile computing device 350.

The mobile computing device 350 may be implemented in a number of different forms, as shown in the figure. For example, it may be implemented as a cellular telephone 380. It may also be implemented as part of a smart-phone 382, personal digital assistant, or other similar mobile device.
